"Boiling water is added and, four minutes later, she brings
her face so close to the liquid it leaves a tiny brown stain on
her nose. She inhales deeply. Five more minutes pass and she dips
her spoon into the coffee. Then she slurps in a short and
powerful burst, sucking in air with the coffee to 'bring a boost
in the sensory effects.' She spits the coffee into a
bowl."

Marsot then assigns scores to the coffee on elements like
balance and sweetness.

The samples she selects are purchased from suppliers and
eventually end up in restaurants.

Marsot also travels to different states to test the quality
of the coffee there.

So how can someone get a job testing coffee?

"Marsot earned degrees in food microbiology and sensory
evaluation in France," according to the Globe. "Before joining
Dunkin’ Brands Group, she trained employees of a liquor company
to taste-test spirits and worked in quality assurance at a ham
and sausage plant."

Marsot also grows coffee plants at home.

Dunkin' Donuts is plotting a massive expansion around America,
meaning that the company will probably need more testers in the
future.
